Control of sub-micron sized particles is of increasing interest as there is clear evidence that small atomic clusters (n = 10-1000 atoms) exhibit novel hybrid properties between...

This proposal aims to explore a cheaper and more environmental-benign surfactant system for yielding efficient water/CO2 microemulsions. The new surfactants permit high...

The project represents a new application of SANS to investigate chemically sophisticated chiral catalysts, addressing important questions in modern synthetic and catalytic...

Using computers to design molecules is a methodology widely adopted in drug discovery to identify targets for synthesis. As molecules increase in size, more computing power is...

A new class of ionic liquids with self-aggregation properties and magnetic activity have been recently reported. Due to the novel behaviour and potential applications, these...

This proposal is to explore the magnetic properties and molecular dynamics of a new class of magnetic ionic liquid surfactants1 (MILSs) (see Fig. 1). The MILSs investigated here...

This proposal aims to explore aqueous phase structures and compositions of a series of mixed surfactants. Although standard surfactant mixtures have been extensively studied...

One application where liquid CO2 has found success is enhanced oil recovery (CO2-EOR) of crude oil from porous rocks. However, a significant disadvantage of using CO2 in EOR is...

Silica has been well-studied dispersed in organic solvents, traditionally called ¿organosols¿. One surfactant that is known to enable dispersion is sodium dioctylsulfosuccinate...

Surfactants are known to charge colloidal surfaces in nonpolar solvents, but only a small number of different molecules have been explored. Recent experiments demonstrate that...

This proposal explores headgroup-free, fluorocarbon-hydrocarbon hybrid compounds able toform viscous elongated aggregates in supercritical CO2 with the aim of improving...

This proposal aims to explore aqueous phase structures and compositions of a series of mixed surfactants. Although standard petrochemically-derived surfactant mixtures have been...

This proposal aims to explore these dispersed lamellar phases with a variety of F7H4 derivatives,to help understand their formation in supercritical CO2 (sc-CO2). The focus is...

Surfactants ability to lower surface tension and act as solubilising agents is critical for their wide use in everyday products. An oily hydrocarbon (HC) "tail group" attached...

This proposal explores headgroup-free, fluorocarbon-hydrocarbon hybrid compounds able toform viscous elongated aggregates in supercritical CO2 with the aim of improving...

Silica has been well-studied as dispersions in organic solvents, traditionally called ¿organosols¿. One surfactant that is known to aid dispersion of silica is cationic...

The aim is use time-resolved SANS to monitor the changes in aggregation structure of the Trost ligand[1] Pd-catalyst [(DACH-phenyl-TSL)Pd+(η3-C6H9)]BArF- 1 (Figure 1 left)...

Recently published results show that SANS is necessary for determining with confidence critical micelle concentrations (CMCs) of inverse micelles in nonpolar solvents.1 The...

The aim of this project is to use SANS to determine if a critical micelle concentration (CMC) exists for the formation of inverse micelles in non-polar solvents. The CMC is a...

The objective is to refine current understanding about the mechanism of hydrotropy with respect to polarity and electrostatic character of hydrotropes and hydrophobic solutes...
